Frequently asked questions

Are clinical trials in Los Angeles safe?
Every trial on this page is registered on ClinicalTrials.gov, the official NIH registry, and is overseen by an Institutional Review Board (IRB). Before joining you receive an informed consent document detailing procedures, risks and compensation. Participation is voluntary and you can withdraw at any time.
How do I join a study in Los Angeles, CA?
Pick a study that matches your profile, contact the research site (or apply through the study links on this page), pass a phone pre-screen, then attend an in-person screening visit. If you qualify, you review and sign the informed consent and the study begins. The process typically takes 1-3 weeks.
Is compensation for clinical trials taxable?
In the U.S., clinical trial compensation is generally considered taxable income, and research sites may issue a 1099 form for payments above $600 in a year. Reimbursements for travel or meals are typically treated differently. Consult a tax professional for your situation.

Can I be in more than one clinical trial at a time?
